Application filed January 30, 1901. Serial No. 5,386. (No model-l To'HJ/Z 71171/0771/ it 'may concern:

Beit known that I, TITO ROSATE a subject ofthe King of Italy, and aresident of Florence, Italy, have invented certain new and usefulImprovementsin Electric Gables, ot' which the following is aspecification.

My invention relates more particularly to cables having surroundingsheaths or protectors; and the object of the invention is to provide animproved form of coupling for connecting the sections of the conductorand its encircling sheath or tube.

The invention is illustrated in the accoinpanying drawings, in which-Figure l is a longitudinal section; Fig. 2, an elevation, and Fig. 2 across-section.

In the drawings, a indicates the conductor, and b the sheath orprotector, which consists of a metallic tube formedl in sectionscorresponding approximately in number and length to the sections a ofthe conductor. The adjoining ends f of the conductor are threaded andare engaged by a small copper rod g and a tubular coupling-'sleeve 7L,having its ends threaded to engage the ends of the conductor-sections. Alarge sleeve c encircles the inner sleeve and in like manner connectsthe adjoining ends of the tubes Z). All opening is provided in thisouter sleeve, closed by a screw-plug e, and this opening alines with anopening in the inner sleeve, through which a suitable filling materialmay be introduced.

I declare that what I claim is- In combination an inner cable composedof sections, hollow coupling-sleeves connecting the ends of saidsections and having an opening therein, tube-sections encircling saidcable-sections and having couplings connecting the adjoining endsthereof, said outer coupling-sleeves having an opening alining with theopening in the inner coupling-sleeve and means for closing said opening,substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses. A
